Timer with clock function

Abstract

The invention discloses a timer with a clock function. The timer comprises a driving device for supplying power, a timing device for setting a time alarm, a gear transmission system for conducting power of the driving device to the timing device, and a micro-switch for switching on / off a power supply plug / socket under the control of the timing device, wherein the timing device comprises an inserting sheet for setting a timing point, an index ring for mounting the inserting sheet, and a scale ring for fixing the inserting sheet on the index ring; the gear transmission system is connected with a pointer for indicating the time alarm; the pointer comprises an hour needle and a minute needle; and the driving device drives the gear transmission system through the index ring. The driving device provided by the scheme is in an integrated structure, so that a motor and each reducing gear are mounted in a shell and are output through a power output shaft. Therefore, the complex steps for mounting the driving device are reduced; the stability of the timer is enhanced; and the cost and the matching and precision requirements on an element process can be reduced. The driving device drives the timing device through the index ring and thus the timing efficiency of the timer is improved.

Description

technical field [0001] The invention relates to a timing device, in particular to a mechanical timer with hour and minute hand indicating functions. Background technique [0002] The timers in the prior art generally include a motor, a micro switch, and a timing device for setting the time. The working principle is that the motor drives the gear to drive the timing device to work. The switch acts to disconnect the controlled circuit. The timer driving device in the prior art is a discrete component, the assembly process of the discrete component is complicated and costly, and a high degree of cooperation is required between the gears. There are requirements for the precision of each component size, and defective products appearing in production higher. Difficult to control. The timing range of this type of timer is generally 24 hours or a cycle, that is, the scale circle on the timing device works in a circle after 24 hours or a week, that is, all timing points will be tr...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the driving device of the timer in the prior art adopts the installation method of separate components, which leads to complicated installation procedures, high coordination and precision required by each component, and high cost, the present invention provides a timing timer using an hour hand and minute hand structure. The timer, this program can not only set the time point of the time to the minute, but also the hour hand adopts a 24-hour timing system, which can rotate for two weeks, which is completely consistent with the common clock, which greatly facilitates the user
